Abstract
Paper presents the process capabilities for solidification hazardous waste. In the first part of the article the authors present general technologies and methods in a comparative model. The following section describes the results of market research for the most advanced and innovative solidification technologies. Comparative analysis of the material has shown and described the three most promising, leading-edge technologies of waste solidification avalible on the Polish market.
Highlights
Solidification of waste referred as chemical immobilization, is the process of waste disposal using their physicochemical properties [1, 5]
Solidification is currently one of the most popular methods of waste disposal for inorganic [4] hazardous waste contained in lands and sludges
It is necessary to ensure the consistency of the composition of the waste stream. This means carrying out costly chemical analyzes of each batch of the batch
Summary
Solidification of waste referred as chemical immobilization, is the process of waste disposal using their physicochemical properties [1, 5]. Noticeable is the fact that the process of waste immobilization counteracts the leaching of harmful to the environment soluble metal compounds such as: - ashes and slags from thermal processes; - industrial dusts and muds; - waste from the chemical industry; - waste from galvanic processes. Solidification is currently one of the most popular methods of waste disposal for inorganic [4] (or with a small admixture of organics) hazardous waste contained in lands and sludges. It serves for the treatment of sewage sludge contaminated with heavy metals. The U.S EPA (Environmental Protection Agency) defines this technology as the best available technology (BAT) for the disposal of about 60 types of hazardous waste
